我已將應用程序暫時存儲在存儲中一段時間,但它偶爾會根據開發人員控制檯中的崩潰報告崩潰,並說: java.lang.ClassCastException in android.widget.ProgressBar.onRestoreInstanceState
與堆棧跟蹤:android.widget.ProgressBar.onRestoreInstanceState中的Unexplainable ClassCastException

這些崩潰的原因沒有迴避我,我無法在我的任何設備上重現它。我沒有在任何地方覆蓋onRestoreInstanceState
。任何人都可以指出我有意義的方向嗎?
你能發佈你的設備信息嗎? – petey 2013-03-08 16:05:52
